Title: Single chip microcomputer
Inventor: SAITO MIKIO
IPC: G06F12/06
Filed: 1988-12-14
Abstract: PURPOSE:To reduce the load of program development by providing a single chip computer including a single EPROM with a means for executing operation equivalent to a device having different memory capacity. CONSTITUTION:When a reset terminal 14 is turned to 'H', the outputs of OR gates 15, 16 are turned to 'H', the output of an inverter 44 is turned to 'L' and other logical gates to which the output signals of X and Y decoders 9, 10 are inputted output 'L' signals. Thereby, a specific EPROM cell 17 is surely selected at the time of reset. The data of the cell 17 are inputted to a buffer 12 and a latch 18. When the terminal 14 is turned to 'L', a program is executed. When the output of the latch 18 is 'L', the output of an AND gate 19 is 'L', and when one of a signal consisting of the most significant bit and a signal consisting of the succeeding bit is 'H', the output of an OR gate 20 is 'H' and the output of an inverter 24 is 'L' to inhibit the output of the data in the cell 17 to a bus 13 is inhibited. When the output of the latch 18 is 'H', the output of the data to the bus 13 is similarly inhibited. At the time of releasing the reset, a memory space can be determined.

Title: Movable coil type linear motor
Inventor: SASAKI TAKASHI
IPC: H02K41/02
Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To suppress torque ripple very small, and improve the linearity of thrust by forming a cover, using material where a ferromagnetic part and a nonmagnetic part coexist, and also, providing the nonmagnetic part in the section to suppress the short-circuited magnetic fluxes. SOLUTION: Then, as occasion demands, the cover 11 is divided into plural numbers in the units where the ferromagnetic parts 11a and the nonmagnetic parts 11bh coexist. The substantial thickness of magnetic space 5 becomes the interval Lg between a pair of ferromagnetic parts 11a and 11a by arranging this cover 11. Hereby, the intensity of the magnetic field of the magnetic space becomes roughly the same as the case that a pair of permanent magnets 4a and 4a each having, as it were, a thickness to are counterposed to each other, and large thrust can be given to a mover. Moreover, since it suppresses short circuit magnetic fluxes f2, favorable linearity can be given to the mover.

Abstract: PURPOSE: To reduce circuit size and power consumption and to furthermore stabilize the operation of an output circuit in an AGC circuit for converting the amplitude of an electric signal in which the amplitude variation of an optical input signal is expressed still as the amplitude variation even after converting the optical input signal into an electric signal by an optical signal receiving part into a fixed value. CONSTITUTION: The AGC circuit is constituted of a variable gain means 10, an amplitude detecting means 20 and a gain controlling means 30. The means 10 variably amplifies an electric input signal followed by the variation of amplitude under control by an amplitude control signal outputted from the means 30, the means 20 detects the amplitude value of an output signal from the means 10 and the means 30 generates the amplitude control signal for the amplitude value and feeds back the control signal to the means 10. Consequently the amplitude variation of an input signal can be converted into fixed amplitude and the amplitude-fixed signal can be outputted by controlling the gain of the means 10.

IPC: G06F17/30
Filed: 1993-11-22
Abstract: PURPOSE:To provide a document retrieval device and method therefor which are capable of easily registering a new document without hindering a retrieval processing and easily retrieving the registered document. CONSTITUTION:The registration of a new document can be early performed and a retrieval can be also performed just after the registration by registering the new document in a small sub-index rather than a main index when the new document is registered in the index, performing a retrieval by performing an access to each index at the time of the retrieval, summing up the result and defining it as a retrieval result. In particular, by providing the sub-index on a high speed main storage device 12, the possiblity of the lowering of retrieval processing speed is eliminated. When the sub-index becomes large, the registration time of the new document is shortened and the possiblity of hindering the retrieval processing is eliminated if the sub-index is appropriately merged into the main index and the size of the sub-index is suppressed when the retrieval processing is not performed, etc.

A selection means 2 uses the output of the means 1 and a multiplicand as inputs to output the multiplicand when the output of the means 5 is positive and to output the output of the means 1 as it is when the output of the means 5 is negative. A gain detection means 6 uses a multiplier as an input to obtain the absolute value of the input and outputs the relevant number 1 or 3. A delay means 3 uses the output of the means 2 as an input to output 0 with the output of the means 6 equal to 1 and to output a number double as much as the input with the output of the means 6 equal to 3 respectively. An addition means 4 outputs the number obtained by adding together the outputs of both means 2 and 3. Thus the multiplication is possible between a multiplicand and + or -1 and + or -3 respectively. Then the output of the means 4 is set at 0 with a multiplicand equal to 0.

Filed: 1989-12-09
Abstract: PURPOSE:To improve the responsiveness of a controller by acting control pressure corresponding to solenoid current depending on a proportional electromagnetic relief valve onto one side of a spool of a secondary control valve to make setting pressure variable for linearly controlling secondary pressure. CONSTITUTION:Discharge pressure of a pump 34 is regulated to make control pressure corresponding to solenoid current Is depending on a proportional electromagnetic relief valve 55 act on one side of a spool 52 of a secondary control valve 50 to control secondary pressure Ps of a secondary cylinder 24, and setting pressure produced by a spring 53 therefore becomes variable for linearly controlling secondary pressure Ps to the solenoid current Is. The electromagnetic control unit 70 determines target secondary pressure, and supplies the solenoid current Is corresponding to the above secondary pressure to linearly control the secondary pressure Ps. Thus troubles such as the abnormal rising of the secondary pressure or the like does not occur, and moreover volume and oil pathes for the control pressure can be reduced to produce the better responsiveness and downsizing of a controller.
